Quicksense™ Si1102

Optical Proximity Detector

Silicon Labs

The QuickSense™ Si1102 is the industry’s most sensitive active infrared proximity sensor IC enabling innovative touchless human interface applications with ultra-low power advantages. Consisting of an infrared LED driver, an infrared photodiode and control logic, this device is packaged in a 3mm x 3mm clear DFN.

Product Description

The high-sensitivity infrared photodiode provides a single-pulse infrared proximity measurement offering customers an opportunity to implement infrared light emitting diodes with unusually low power levels.

  • High-performance proximity detector with a sensing range of up to 50 cm
  • Single-pulse sensing mode for low system power
  • Adjustable detection threshold and strobe frequency
  • Proximity (PRX) status latch enables controlling devices to avoid missing a detection
  • High EMI immunity without shielded packaging
  • 2 to 5.25 V power supply
  • Operating temperature range: –40°C to +85°C
  • Typical 10µA current consumption and ultra-low power of 1mA typical
  • Current driven (400mA) or saturated LED driver output
  • Small outline: 3x3mm (ODFN)
